LOCKING DEVICE.

Application filed December 29, 1924. Serial No. 758,652..

This invention relates to locks for ward robe trunks and has for one of its objects to provide a duplex locking mechanism for the sections of such trunks wherein one of the locking mechanisms is controlled or actuated by the other, which latter in turn is manually controlled by a key.

A further object of the invention is to provide a lock of the class described which will positively and eiiicient-ly draw the two sections together into'clamping engagement and which will prevent the locking of the key controlled mechanism, until the sections are in such condition.

'A still further object of the invention is to provide a mechanism of the class described which will be simple in construction, comparatively inexpens've to manufacture and more efiicient in use than those heretotore proposed.

With the above and other objects in view which will appear as the description proceeds, the invention consists in the novel details of construction and combinations and arrangements of parts more fully hereinatter disclosed and particularly pointed out in the appended claims.

Referring to the accompanying drawings in which like numerals designate like parts in all the views, a

Figure 1 is a fragmentary sectional View of a wardrobe a trunk showing a locking mechanism constructed in accordance with the present invention applied thereto, the parts being shown-in locked position.

Figure 2 is an enlarged horizontal sectional view taken approximately. on the plane indicated by the line 22 of Figure 1, the parts bein shown in the unlocked position however. 1

' Figure 3 is an enlarged sectional detail view taken approximately on the plane indicated by the line 33 of Figure 1, looking in the direction of the arrows, and

Figure 4 is a view similar to Figure 3, but taken approximately on the plane indicated by the line -d of Figure 2. i 7

Referring more particularly to the said drawings, the numeral 5 indicates generally a wardrobe trunk comprising the sections 6 and 7, the former of which has secured to it, a hasp member 8 comprising three sections 9, 10 and 11, which are pivotally connected together as at 12 and 13 respectively, (see Figures 1 and 2). The section 9 of the hasp member is rigidly secured to the Wflll of the trunk section 6 in any suitable and well known manner, while the section 11 carries a suitable key lock 14, as shown in Figure 2. The said section 11 is also provided with an angularly bent member or projection 15, which serves as an actuating member for certain other parts of the mechanism as will appear more fully below.

The wall of the trunk section 7 is recessed as indicated at 16 (see Figure 2), the said recess extending only partially through said wall as will be readily understood. A

slidable plate or member 17 is mounted in the said recess 16 and is retained therein by means of suitable guides 18 (see Figures 2' and 4). The said member 17 is provided with an angularly extendingtoe 19 which is adapted to be engaged by the projection 15 of the hasp'member 11 as the latter is .swung to closed position about the hinge pins 12 and 13, whereby the slidable 111ember 17 will be moved toward the left from the position shown in Figure 2, as will be readily understood.

The said slidable member 17 carries a stud or pin 20, which projects through a slot 21,

cut in the wall of the trunk section 7 which pin is received in an elongated slot 22 formed in one arm 23 of a bell crank lever 24 which is pivotally mounted as at 25 on the wall of the trunk section 7. The other.

arm 26 of the said bell crank lever is pivot ally connected as at 27 to one end of a vertically extending link 28 the other endof which is pivotally connected as by a pin 29 to an actuating member 30, mounted within the casing 31 of a separate locking mechanism which is preferably located,adjacent the lower portions of the trunk sections 6 and 7 (see Figure 1). This said locking mechanism may be of any suitable construction, the details of which constitute no part of the present'invention, but for illustrative purposes, there is here shown a mechanism, including a slidable member 32 having rack teeth 33 adapted to be engaged by gear teeth 34 formed upon one end of the actuconstruction is quite similar to that described and claimed in the co-pending application of Martin Rasmussen. filed July 7, 1923, Serial No. 650,18S, entitled Trunk locks.

The casing 310i the lower locking member is provided with an arcuate slot 38 to accommodate the pin 29 as will be readily understood from Figure 1. A tension spring 40 has oneend secured as at 41 to the arm 26 of the bell crank lever 2%, while its otiier end is secured as at 42 to the wall of the trunk section 7, so that the said spring always tends to move the parts to unlocked position. 7

The trunk section 7 is also recessed as at L3 to receive an escutcheon plate 454 of substantially the same shape shown in Figure 2, which plate receives the'locking member 14 carried by the hasp member 11 when the parts are in closed positions. The slidable member 17 is so constructed and arranged that when it is in the open position, its right hand end as viewed in Figures 1 and 2, projects through the side of the escutcheon plate 44 and into the lower portion of the recess 15 so that unless the part. are completely closed, it will be impossible to fully introduce the locking member 1% into the said recess 45 and'lock the same.

It thus results that until the projection 15 of the hasp member 11 has engaged the toe 19 and moved the slidable member 17 completely toward the left, as viewed in Figure 2, so that the clamping action of the lower locking mechanism has been fully completed, it willbe impossible to lock the hasp member by means of the key lock let.

lVhile one form of the invention has been illustrated and described, it is obvious that those skilled in the art may vary the details of construction as well as the precise arrangement of parts without departing from the spirit of the invention and therefore it is not wished. to be limited to the above disclosure except as may be required by the claims.

Having thus described my invention what I desire to claim as new is:

1. The combination with a trunk having two registering sections of a pair of lock mechanisms, one of which is provided with an outwardly swinging hasp; an escutcheon plate carried by one of said trunk sections for receiving a portion of said hasp; operating connections between said lock mechanisms, including a slidable member adapted in one position to prevent said hasp portion from entering. said plate; means carried by said hasp for moving said slidable member and connections in one direction; and addiby the other tional means for moving said connections in "the other direction.

2. In a trunk lock, a pivoted hasp provided with a projection; a slidable member provided with a toe adapted to be engaged by said projection; a separate lock mechanism spaced from said hasj and lever and link connections between said slidable member and said mechanism, whereby movements of the former will actuate the latter.

3. In a trunk lock, a pivoted hasp' provided with a projection; a slidable member provided witn a toe adapted to be engaged 3y said projection; a bell crank lever. one arm of which is connected to said slidable member; a link, one end of which is connected to the other arm oi said bell crank lever; and a separate lockmechanism spaced from said hasp, having an actuating member connected to the other end of said link.

In a trunk, a pair of cooperating sections, one of which is provided with a recess and a slot: a slidable member mounted in said recess, provided with a pin projecting through said slot, a hasp pivotally carried 'i' said sections, adapted to engage and move said slidableinember; a bell crank lever pivotally carried by said recessed trunk section, one arm of which engages said pin; a separate lock mechanism spaced from said hasp; including a casing having a slot, and an actuating member having a pin projecting through said slot; and a link, one end'ot which receives said last named pin and the other end of which is connected to the other arm of said bell crank lever.

5. In a trunk, a pair of cooperating sec tions, one of which is provided with a recess and a slot; a slidable member mounted in said recess; provided with a toe and with a pin projecting through said slot; at hasp pivotally carried by the other of said sections provided with an angular projection adapted to engage said toe and move said slidable member in one direction; a bell crank lever pivotally carried by said recessed trunk section; one arm of which engages said pin; a spring connected to said lever, for moving said slidable member in the other direction, a separate lock mechanism spaced from said hasp, including a casing having a slot, and an actuating member having a pin projecting through said slot; and a link, one end of which receives said last named pin and the other end or which is connected to the other arm of said bell crank lever.

In testimony whereof, I aliix my signature.
